I'm sorry you're going through this.
I don't know much about it except I know my mother-in-lawn saw her own psychiatrist and was denied. She was told you're never approved on the first try. So, on the second try she had to go to see the SSI psychiatrsit and he agreed with her dx of Bipolar 1, and because he agreed she got it no problem.
So, have you seen their psychiatrist? I don't know it might work differently in different states.

But that's what happened with her.
